Step-by-step explanation:
neg 4(x+2)= -2
(4×4)=16
+( -2)=14
14
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
Answer:91
Step-by-step explanation:
87.5/100=.875, .875*104=91
I would say -13 because y = - 10 - 3 would mean that what ever -10 minus 3 equals is what y equals and -10 - 3 is -13
