4(2x  3) + 5(x + 1)
= 4(2x) + 4(3) + 5(x) + 5(1) {used distributive property}
= 8x  12 + 5x + 5 {multiplied through}
= 13x  7 {combined like terms}

Distributive property: x(a + b) = ax + bx
In other words, multiply the outside number to each term on the inside of the group.
4(2x  3) + 5(x + 1) (distribute 4 and 5 to their groups)
8x  12 + 5x + 5 (combine like terms)
13x  7 <===ANSWER
In other words, multiply the outside number to each term on the inside of the group.
4(2x  3) + 5(x + 1) (distribute 4 and 5 to their groups)
8x  12 + 5x + 5 (combine like terms)
13x  7 <===ANSWER

Multiply every inside the parenthesis by the number in front of it
8x  12 + 5x + 5
Put together like terms.
13x  7
you're done!
8x  12 + 5x + 5
Put together like terms.
13x  7
you're done!

4(2x3)+5(x+1)
= (4*2x  4*3) + (5*x + 5*1)
= (8x  12) + (5x + 5)
= 8x  12 + 5x + 5
= (8x + 5x) + (12 + 5)
= 13x  7
= (4*2x  4*3) + (5*x + 5*1)
= (8x  12) + (5x + 5)
= 8x  12 + 5x + 5
= (8x + 5x) + (12 + 5)
= 13x  7

Just use distributive property.
Answer: 8x12+5x+1=13x11
Answer: 8x12+5x+1=13x11
