Sagot :
Answer:
okay so x=-3, y=4
Step-by-step explanation:
based off the top of my head -3+5*4=17 and -4*-3=12 12+3*4=24
Answer:
x=-3 ,y=4
Step-by-step explanation:
x+5y=17------(i)
-4x+3y=24------(ii)
use substitution method
x+5y=17
make x subject of the formula
x=17-5y-----(iii)
substitute equation (iii) into equation (ii)
-4x+3y=24
-4(17-5y)+3y=24
-68+20y+3y=24
23y=24+68
23y=92
divide both sides by 23
y=92/23
y=4
substitute y in equation (iii)
x=17-5y
x=17-5(4)
x=17-20
x=-3
