bahrom7893 · Answer

what they are asking you is:
What are x and y when:
-7/8x+1/4 = -3/4x+1/2

selena2345 · Answer

yes

bahrom7893 · Answer

solve for x, then plug whatever value you get back into either of those equations to get y. That will be your answer.

can u show me please ?

bahrom7893 · Answer

Multiply everything by 8:
-7x + 2 = -6x + 4
Move the terms with x to one and the rest to the other side:
-7x + 6x = 4 - 2
Simplify:
-x = 2
x = -2

selena2345 · Answer

can give me an example of that ?

bahrom7893 · Answer

y=-7/8x+1/4 = -7*-2/8 + 1/4 = 14/8 + 1/4 = 7/4 + 1/4 = 8/4 = 2

bahrom7893 · Answer

(x, y) = (-2, 2)
