Okay so set up the equation to be
10b+45 = 6b+77
Okay Step 2: -6b from both sides and subtract 45 from both sides. Then your equation should look like...
2b = 32
Step 3: divide both sides by 2. Which should leave you with....
B=16
Now that we know B we have to plug it in so to solve for H the equation will be...
10(16)+45=205
That’s all!!
