To solve the first equation 2,7+1,9=2x+1,5, we need to add the decimals on the left side and set it equal to 2x+1.5 on the right side.
2.7 + 1.9 = 4.4.6 = 2x + 1.5
Now solve for x2x = 4.6 - 1.2x = 3.x = 3.1 / x = 1.55
So, x = 1.55 for the first equation.
Next, to solve the second equation 13/18x + 13 = 7/12x + 8, we need to simplify it.
Multiply through by the least common multiple (LCM) of 18 and 12 to get rid of the fractions:
12(13/18)x + 12(13) = 18(7/12)x + 18(813(12)x + 156 = 7(18)x + 14156x + 156 = 126x + 144
Now solve for x156x - 126x = 144 - 1530x = -1x = -12 / 3x = -0.4
So, x = -0.4 for the second equation.
To solve the first equation 2,7+1,9=2x+1,5, we need to add the decimals on the left side and set it equal to 2x+1.5 on the right side.
2.7 + 1.9 = 4.
4.6 = 2x + 1.5
Now solve for x
2x = 4.6 - 1.
2x = 3.
x = 3.1 /
x = 1.55
So, x = 1.55 for the first equation.
Next, to solve the second equation 13/18x + 13 = 7/12x + 8, we need to simplify it.
Multiply through by the least common multiple (LCM) of 18 and 12 to get rid of the fractions:
12(13/18)x + 12(13) = 18(7/12)x + 18(8
13(12)x + 156 = 7(18)x + 14
156x + 156 = 126x + 144
Now solve for x
156x - 126x = 144 - 15
30x = -1
x = -12 / 3
x = -0.4
So, x = -0.4 for the second equation.
