The expression into an equivalent form 6(0.7y+0.8z)−4z−6(−0.1z−0.6y) would be; 7.8y + 1.4z
Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need the expression into an equivalent form;
6(0.7y+0.8z)−4z−6(−0.1z−0.6y)
This expression could also be given by;
6(0.7y+0.8z)−4z−6(−0.1z−0.6y)
Now, we know that:
4.2y + 4.8z - 4z + 0.6z + 3.6y
Now
7.8y + 1.4z
Hence, the expression into an equivalent form 6(0.7y+0.8z)−4z−6(−0.1z−0.6y) would be; 7.8y + 1.4z
