Replace the value of a in the equation 6a+3 So 6x6+3=36+3=39.
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2

a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
Replace the value of a in the equation 6a+3 So 6x6+3=36+3=39.
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2

6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
(4, 3)
a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a
9a = 6a + 4 subtracting 6a from each side, 3a = 4 dividing each side by 3, a = 4/3
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
-4 + 10 + 6a - 2a + 3 9 + 4a
7A + 3
a + 6a - 9 = 30 7a - 9 = 30 7a = 30 + 9 7a = 39 a = 39/7 a = 5.571 (to 3 decimal places only).
