Question

Alguém pode me ajudar com essas equações.
2×+1=4
2
10×+3=9 ​

Answer 1

2x + 1 = 4
2x = 4 - 1
x = 3/2 ou 1,5

10x + 3 = 9
10x = 9 - 3
x = 6/10

Answer 2

Let's solve your equation step-by-step.

2x+1=4

Step 1: Subtract 1 from both sides.

2x+1−1=4−1

2x=3

Step 2: Divide both sides by 2.

2x/2 = 3/2

x = 3/2

10x + 3 = 9

10x = 9 - 3

x = 6/10
