Solve the following system of equations. enter the y-coordinate of the solution. round your answer to the nearest tenth 5x+2y=7 -2x+6y=9 is it (0.7,1.

The solution to the system of equations is (0.7, 1.7)

The given system of equations is:

5x  +   2y   =   7(1)

-2x  +  6y   =  9(2)

Multiply equation (1) by 2

10x   +  4y   =   14(3)

Multiply equation (2) by 5

-10x  +  30y   =   45(4)

Add equations (3) and (4)

34y   =   59

y   =  59/34

y   =  1.7 (to the nearest tenth)

Substitute y = 1.7 into equation (1)

5x  +  2y  =  7

5x   +  2(1.7)  =  7

5x  +  3.4   =  7

5x   =  7  -  3.4

5x   =   3.6

x    =   3.6 / 5

x    =  0.7

The solution to the system of equations is (0.7, 1.7)
