1. Multiply a number by 4, then multiply this product by 5, then you get 80
Whats the way to solve it, the equation.
2. Add 4 to a number, then subtract 5 from the sum, and you get 43
Whats the equation to solving that
if anyone can answer either of those,
that'd be great.
1. 4*X*5=20X=80
2. (x+4)-5=43
To solve the equation, let's break it down step by step:
1. Multiply a number by 4.
Let's call the number "X". So, we have 4 * X as the first step.
2. Multiply this product by 5.
Take the result of step 1, which is 4 * X, and multiply it by 5. Therefore, the equation becomes (4 * X) * 5.
3. Set the equation equal to 80.
According to the problem statement, the result of the previous step should be equal to 80. So, the final equation is (4 * X) * 5 = 80.
To solve this equation, you can follow these steps:
Step 1: Simplify the equation.
(4 * X) * 5 simplifies to 20X.
Step 2: Set the equation equal to 80.
Now, the simplified equation becomes 20X = 80.
Step 3: Solve for X.
Divide both sides of the equation by 20, which gives you X = 80 / 20. Simplifying further, you have X = 4.
Therefore, the solution to the first equation is X = 4.
Now, let's move on to the second equation:
1. Add 4 to a number.
Similar to the first problem, let's call the number "X". Thus, the first step is to add 4 to X.
2. Subtract 5 from the sum.
Take the result from step 1, which is X + 4, and subtract 5 from it. Consequently, the equation becomes (X + 4) - 5.
3. Set the equation equal to 43.
According to the problem statement, the result of the previous step should be equal to 43. So, the final equation is (X + 4) - 5 = 43.
To solve this equation, you can follow these steps:
Step 1: Simplify the equation.
(X + 4) - 5 simplifies to X - 1.
Step 2: Set the equation equal to 43.
Now, the simplified equation becomes X - 1 = 43.
Step 3: Solve for X.
Add 1 to both sides of the equation, which gives you X = 43 + 1. Simplifying further, you have X = 44.
Therefore, the solution to the second equation is X = 44.
