Solve the system of equations - System 1: 7x + 2y = 24
System 2: 8x + 2y = 30

Will mark brainliest.

x=6

y=-9

Step-by-step explanation:

x=6, y=-9

Step-by-step explanation:

System 2 - System 1:

8x+2y - (7x+2y) = 30-24

8x-7x +2y-2y = 6

x=6

Substitute the value of x in System 1:

7*6 +2y = 24

42 + 2y = 24

2y = 24-42

2y = -18

y = -9

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
