= a + b - 2
3a=3xa and if a = 5 it would be 3x5 which = 15 2b=2xb and if b = 2 it would be 2x2 which = 4 15+4=19
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
A = 2 and B = 2 3(2) - 2(2) = 6 - 4 = 2.
sample problem 9b + 3a - a + 6+ 2b + 4 terms would be each number or number plus a variable separated by an operation symbol (+ or -) like terms would be 9b and 2b, 3a and -a, and 6 and 4 simply add 9b + 2b (which is 11b) 3a-a (which is 2a) and 6 + 4 (which is 10) your answer would then be 11b + 2a + 10 hope that helped

3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2

A = 2 and B = 2 3(2) - 2(2) = 6 - 4 = 2.
a is equal to 4
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
sample problem 9b + 3a - a + 6+ 2b + 4 terms would be each number or number plus a variable separated by an operation symbol (+ or -) like terms would be 9b and 2b, 3a and -a, and 6 and 4 simply add 9b + 2b (which is 11b) 3a-a (which is 2a) and 6 + 4 (which is 10) your answer would then be 11b + 2a + 10 hope that helped
