Answer:
m=-4
Step-by-step explanation:
5m-10m=-10m+5m=-(10m-5m)=-5m=20
divide by 5 on both sides, -m=4
miltiply by -1 on both sides, m=-4
Answer:
0.33
Step-by-step explanation:
X-4y=28
8x+4y=8
---------------
9x=36→x=4
4-4y=28→y=6
—-----------------------------------------------------------
y-5=x
4(y-5)-y=4
4y-20-y=4
3y=24
y=8
x8-5=3
For the first one your answer would be
The problem would stay the same because you can't combine like terms.
For the second one your answer would be
-8y-5x=13
It's an equilateral triangle so each angle = 60°
2x-4=60
2x=64
x=32
