Question

0,5×(x+1,6)+1,4×(3x+2,4)=9,8

Answer 1

0,5×(x+1,6)+1,4×(3x+2,4)=9,8
0,5х+0,8+4,2х+3,36=9,8
4,7х+4,16=9,8
4,7х=5,64
х=1,2

Answer 2

0,5(x+1,6)+1,4(3x+2,4)=9,8
0,5x+0,8+4,2x+3,36=9,8
4,7x=9,8-0,8-3,36
4,7x=5,64
x=5,64:4,7
x=1,2

Answer 3

To solve the equation, you need to find the value of 'x' that satisfies the equation:

0.5*(x+1.6) + 1.4*(3x+2.4) = 9.8

Let's solve it step-by-step:

Step 1: Distribute the coefficients. 0.5x + 0.51.6 + 1.43x + 1.4*2.4 = 9.8

Step 2: Simplify. 0.5x + 0.8 + 4.2x + 3.36 = 9.8

Step 3: Combine like terms. (0.5x + 4.2x) + (0.8 + 3.36) = 9.8 4.7x + 4.16 = 9.8

Step 4: Move the constant term to the other side of the equation. 4.7x = 9.8 - 4.16 4.7x = 5.64

Step 5: Solve for 'x'. x = 5.64 / 4.7 x ≈ 1.2

So, the value of 'x' that satisfies the equation is approximately x = 1.2.
