Solve the equation. Round to the nearest hundredth:
1. 1.59x+4.23=3.56x+2.12
2. -3(1.25-2.48x)=8.15+5.86
1.59x+4.23=3.56x+2.12
1.59x - 3.56x = 2.12 - 4.23
-1.97x = -2.11
x = -2.11/-1.97 = appr. 1.071
for the second
-3(1.25-2.48x)=8.15+5.86
-3.75 + 7.44x = 14.01
7.44x = 14.01 + 3.75
7.44x = 17.76
x = appr. 2.387
