Isolate x on one side of the equation.
15+4x=3x-7
15+4x-4x=3x-7-4x
15=-7-x
15+7=-7+7-x
22=-x
x=-22
The equation is asking you to multiply.
= 4 * -7
= -28

Answer:
13.86
Step-by-step explanation: First- (2.3 * 4/10)
which gives you 27/10
Then (4.16 * 7/1)
Which gives you 11.16/1 (basically 11.16)
Then divide 27/10 which gives you 2.7
add 11.16+2.7
which adds up to 13.86
