7 p + 12 = 3 p + 11 7 p − 3 p = 11 − 12 4 p = − 1 / : 4 p = − 4 1
7p+12=3p+11 12-11=3p-7p 1=-4p 1/-4=p -0.25=p
We can express the equation 7 p + 12 = 3 p + 11 as 4 p = − 1 by isolating the variable p and combining constants. This takes the initial equation and simplifies it to focus on the relationship involving p alone. The final equivalent form is clearer and shows that four times the variable equals negative one.
