Question

May someone please help me?

Answer 1

y = 5x + 7 ---1

y = 7x + 8 ---2

Substitute either one of the equations into the other.

I will substitute 1 into 2.

5x + 7 = 7x + 8

Simplify and solve for x.

2x = -1

x = -1/2

Substitute x into either one of the equations to find y.

I will substitute x into 1.

y = 5(-1/2) + 7

= 9/2

Hence, x = -1/2, y = 9/2

Answer 2

Answer:
`x=-(1)/(2), y=(9)/(2)`

Explanation:

`5x+7=7x+8\\\\2x=-1\\\\x=-(1)/(2)\\\\\implies y=5\left(-(1)/(2) \right)+7=(9)/(2)`
