Answer:
see explanation
Step-by-step explanation:
1
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
2
7m = 8 + 5m ( subtract 5m from both sides )
2m = 8 ( divide both sides by 2 )
m = 4
3
2a = 9 - a ( add a to both sides )
3a = 9 ( divide both sides by 3 )
a = 3
4
[tex]\frac{1}{4}[/tex] d = 3 ( multiply both sides by 4 to clear the fraction )
d = 3 × 4 = 12
5
5y + 6 = 21 ( subtract 6 from both sides )
5y = 15 ( divide both sides by 5 )
y = 3
6
2n - 3 = 6 ( add 3 to both sides )
2n = 9 ( divide both sides by 2 )
n = 4.5
