We just found that a = -0.1 in this system of equations: 3 = 10a + b 2= 20a + b. find the value of b.

Step-by-step explanation:

Put a = -0.1 to the first an second equation and find velue of b:

3 = 10a + b

3 = 10(-0.1) + b

3 = -1 + b             add 1 to both sides

4 = b → b = 4

2 = 20a + b

2 = 20(-0.1) + b

2 = -2 + b       add 2 to both sides

4 = b → b = 4
