Question

solve the equations

a) 4+5(p-1)=34
b) 34-5(p-1)=4​

Answer 1

$1) \: 4 + 5(p - 1) = 34 \\ \\ 4 + 5p - 5 = 34 \\ \\ 4 - 5 + 5p = 34 \\ \\ - 1 + 5p = 34 \\ \\ 5p = 34 + 1 \\ \\ 5p = 35 \\ \\ p = \frac{35}{5} \\ \\ p = 7$

$2) \: 34 - 5(p - 1) = 4 \\ \\ 34 - 5p + 5 = 4 \\ \\ 34 + 5 - 5p = 4 \\ \\ 39 - 5p = 4 \\ \\ - 5p = 4 - 39 \\ \\ - 5p = - 35 \\ \\ p = \frac{ - 35}{ - 5} \\ \\ p = 7$
