Answer
The solution is -5
Work Step by Step
4(2t+5)-21=7t-6 Apply the distributive property
4$\times$ 2t +4$\times$5 -21=7t-6 Multiply
8t+20-21=7t-6 Simplify
8t-1=7t-6 Add 1 to both sides .
8t-1+1=7t-6 +1
8t=7t-5 Subtract 7t from both sides
8t-7t=7t-5-7t
t=-5
The solution is -5
Check
4(2t+5)-21=7t-6 Replace t with -5
4[2(-5)+5]-21=7(-5)-6
4[-10+5]-21=-35-6
4(-5)-21=-41
-20-21=-41
-41=-41
