Solve the systems of equations -4x-4y=20 and 3x-4y=-22

x = - 6,    y = 1

Step-by-step explanation:

-4x - 4y = 20 a

3x - 4y = -22   b

a - b  :   -7x = 42

x = -6

y = (3 x (-6) + 22) /4 = 1    

1010: 3030

is it i think

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
