Evaluate each expression for the given value of the variable.

3 (2a + 5) + 2 (3 - a); a = 4

3 (2a+5) + 2 (3-a); a=4 plug in the a with 4 in the equations

3 (2 (4) + 5) + 2 (3 - (4))

3 (6+5) + 2 (-12)

3 (11) - 24

33-24

=9

3 (2a + 5) + 2 (3 - a)

Substitute 4 for a into the expression.

3[2 (4) + 5] + 2[3 - (4) ]

Multiply 2 * 4 inside the parentheses first.

3 (8 + 5) + 2 (3 - 4)

Solve inside the parentheses.

3 (13) + 2 (-1)

Multiply the numbers together.

39 - 2 = 37

Your answer is 37.
