Question 58048
2x-3y=24 
2x+y=8

to solve this question you must opperate the substitution method the second eqation is easier to simplify and isolate y.

2x+y=8
subtract 2x to isolate y
y=8-2x

now substitute in (8-2x) for y in the first equation
2x-3(8-2x)=24

you have to expand the -3 into the brackets so you get the equation
2x-24+6x=24
add 24 to each side and simplify the equation
8x=48

divide both sides by 8 to isolate x

x=6

to find y substitute 6 in for x to any of the above 2 equations, i recomend the second one as it is easier
2x+y=8
2(6)+y=8
12+y=8
subtract 12 from each side
y=-4

so in this equation you should have calculated that x=6 and y=(-4)
