Answer:
x=4
Step-by-step explanation:
multiply first eq. by 3 and second by 4 to get rid of y
15x+12y=24
8x-12y=68
add the equations
23x = 92
divide both sides by 23
x=92/23=4
Answer:
x = 4
Step-by-step explanation:
Given the 2 equations
5x + 4y = 8 → (1)
2x - 3y = 17 → (2)
Multiplying (1) by 3 and (2) by 4 then adding will eliminate the y- term
15x + 12y = 24 → (3)
8x - 12y = 68 → (4)
Add (3) and (4) term by term to eliminate y, that is
23x = 92 ( divide both sides by 23 )
x = 4
