3a=1divide both sides by 3a=1/3
2a + 3a + 4 = 5a + 4
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7
12+1.5a = 3a 12 = 3a-1.5a 12 = 1.5a Divide both sides by 1.5 to find the value of a: a = 8
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
If a + b = 6, what is the value of 3a + 3b?
3a=1divide both sides by 3a=1/3
2a + 3a + 4 = 5a + 4
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
The value of a is -7
12
10
3a plus 4 equals 3a +4. You can not combine the two parts because they are not like terms so there is no way to simplify this.
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
3a-9 = 6 3a = 6+9 3a = 15 a = 15/3 a = 5 Substitute a = 5 into 4a-1. 4a-1 =4(5)-1 =20-1 =19 Therefore, the value of 4a-1 is 19.
If: -3a-1 = -15 Then: a = 4 and 2/3
