First, you have to use the distributive property to remove your parentheses. So, 4(x + 3) becomes 4x + 12 (multiply the 4 by both things in parentheses, x and 3). Your new problem is: 3x  7 + 4x + 12 = 26 From here, you just need to combine like terms. 3x and 4x are like terms, so we combine them to get 7x. 7 and 12 are like terms so we combine them to get 5. Your new problem is: 7x + 5 = 26 I think you can solve it from there. :)
