Answer 1

solve the problem as a equation eg collect like terms

Explanation:

Answer 2

Explanation:

Sum of all the angles of triangle = 180

∠A + ∠B + ∠C = 180

2x -3 +3x +4 +x -1 = 180

2x + 3x +x - 3 + 4 - 1 = 180

6x + 0 = 180

6x = 180

x = 180/6

x = 30°

∠A = 2x -3 = 2*30 - 3 = 60 - 3 = 57°

∠B = 3x +4 = 3* 30 + 4 = 90 + 4 = 94°

∠C= x - 1 = 30- 1 = 29°
