Answer:
1. 4x + 3 = 11
4x=11−3
4x=8
x= [tex]\frac{8}{4} \\[/tex]
x=2
2. 3a + 4 = -8
3a=−8−4
3a=−12
a= [tex]\frac{-12}{3}[/tex]
a=−4
3. 4x + 8 = 12
4x=12−8
4x=4
x=[tex]\frac{4}{4}[/tex]
x=1
4. 2n - 8 = 12
2n=12+8
2n=20
n=[tex]\frac{20}{2}[/tex]
n=10
5. 3u - 4 = -7
3u=−7+4
3u=−3
u=[tex]\frac{-3}{3}[/tex]
u=−1
