Question

Help me please I’m so tired I can’t keep my eyes open

Answer 1

VW = 9

VX is the whole line
VW and WX makes up VX so:
VW + WX = VW, or:
(4x - 7) + (3x) = (5x + 1); add 3x
7x - 7 = 5x + 1; subtract 5x
2x - 7 = 1; add 7
2x = 8; divide 2
x = 4

Now Put 4 in for VW:
(4(4)-7); multiply
(16-7)
9

Answer 2

Answer:

9

Add VW and WX  and set equal to VX

Solve for x and plug into VW
