Answer:
130x+150y=1,920
Step-by-step explanation:
Why that is the equation is he learned 130 words per month in Portugal and 150 words per month in Brazil. Added together it is 1,920.
So the equation is 130x+150y=1,920.
For y try substracting 112 from 180 wich should give u 60 which is y now add 60 plus 58 which is 118 now substract 118 from 180 which is 62 aka x

Answer:
x=−6
x=2
Step-by-step explanation:
Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.
∣x+2∣−5=−1
Add 5 to both sides of the equation.
∣x+2∣=4
Use the definition of absolute value.
x+2=4
x+2=−4
Subtract 2 from both sides of the equation.
x=2
x=−6
