3y+7=x 5x+4y=-3 x=? y=?

x=-1,\:y=4

Step-by-step explanation:

x = 1

y = -2

Step-by-step explanation:

3y + 7 = x

5x + 4y = -3

Let's use substitution method, plug in the top equation x into the bottom one

5(3y + 7) + 4y = -3

15y + 35 + 4y = -3

19y + 35 = -3

Subtract 35 from both sides

19y + 35 = -3

     - 35    - 35

19y = -38

Divide both sides by 19

19y/19 = -38/19

y = -2

Plug in the new y into one of the original equations, I'll use the top one

3(-2) + 7 = x

-6 + 7 = x

x = 1

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
