Hey I'm in 6th too, Simplify means to solve the prob
3x = -7 Divide both sides by 3. 3 goes into seven twice with one-third left over. Since it's a negative seven, the answer will also be negative.
x = -2
X = 64% of 120
= 64/100 * 120
= (64 * 120) / 100
= 7680 / 100
= 76.8
The number is 76.8
The value of x in the this picture is x=11.5
When simplified the answers results in
= -1
